Question

Solve the expression: $7+(4-3^2÷3)$

• A. 1
• B. 8
• C. 5

Answer 1

The correct option is B 8

The given expression has the operations: addition, parentheses, subtraction, exponent and division.

As per the PEMDAS rule, we must first look into the expression inside the parentheses $\to (4-3^2÷3)$

Here, as per the PEMDAS rule, the exponent must be solved first.

$7+(4-3^2÷3)$
$=7+(4-9÷3)$

Inside the parentheses, the division is in higher priority.

$7+(4-9÷3)$
$=7+(4-3)$

Again we, go for the parenthesis first.

$7+(4-3)$
$=7+1$

At the last, we have addition $\to 7+1=8$

$\therefore 8$ is the value of the expression.
